When you say max out the Closed Loop Bios Tables....do you mean set them to say 740 in all cells.shouldnt be pinging much, over 2000rpm there is a very good knock sensor used, and will take substantial ignition advance out. flash the bike with a smart tune version of the cal and run some record time on it. the 176AE106 cal is pretty good, also after smart tuning max out the closed loop bias tables, that will richen it up a bit more
